Mac OS X Netbook

Putting Mac OS X onto a netbook. Total cost $375 + Mac OS X

Computer: Dell Vostro A90

Upgrades: 16 gb SSD and 2gb DDR2 RAM

Tutorial: http://osx.mechdrew.com/guides/dellefi1.shtml

Quirks:

• towards the end of the tutorial when it says to boot OS X using "-x" user "-x -f" instead which is a force command, when I tried the "-x", all I got was a messed up white display.
• I only had a 8 gb flash drive so i have to use another 2 gb drive to put the 10.5.7 upgrade (unpackaged) and DellEFI onto.
  

Final Notes:

• OS X takes up about 8.3 gb so either get a bigger SSD or get an external drive.
• I picked up a 16 gb SDHC card (since there's a slot for one and it's basically un-noticeable) .
  
• My total price came to about $375 with the upgrades and 16 gb SDHC card for the hardware
• a copy of OS X will be $130 as well.

GWT Formatting Best Practices

• Do NOT use FlexTable to create input forms.
• Use CSS to style elements 
• Use CSS to style column width and alignment
• Use modular code, i.e. group of radio buttons could be a separate method or a class 
• Do NOT use indices to format, rather use logical object and methods

Example 1
Code before re-factoring:

contentTable.getFlexCellFormatter().setWidth(BULLETIN_INDEX_6_ANNOUNCEMENT, 0, "25%");

contentTable.getFlexCellFormatter().setColSpan(BULLETIN_INDEX_12_DESTINATION_MESSAGE, 1, 2);

contentTable.getFlexCellFormatter().setAlignment(BULLETIN_INDEX_0_SPORT, 0, HasHorizontalAlignment.ALIGN_RIGHT, HasVerticalAlignment.ALIGN_MIDDLE);

Code after re-factoring:
myStyles.css:

.admin_message_form_left_column {

width: 170px;

text-align: right;

padding: 5px;

background-color: yellow;

}

.admin_message_form_right_column {

padding: 5px;

background-color: blue;

}

MyClass.java:

this.left.setStyleName("admin_message_form_left_column");

this.right.setStyleName("admin_message_form_right_column");

Example 2

Code before re-factoring:
contentTable.setWidget(BULLETIN_INDEX_1_DIVISION, 0, noWrapLabel("Division:"));
contentTable.setWidget(BULLETIN_INDEX_1_DIVISION, 1, divisionList);

Code after re-factoring:

divSelector.setLeft(noWrapLabel("Division:"));
divSelector.setRight(divisionList);
divSelector.setVisible(true);

SQL: like

Select * from table_a where column_a like '%xxxyyyzz.JPG%'

eBook reader

There was Amazon Kindle, now there is Barnes & Noble Nook... which
motivated me to try iPhone version. With ability to adjust the fonts
and colors of the pages, even the scroll speed I think I might like it
for my soft-cover needs, on the go, and while reading at night. I am
not sure about getting rid of my hard cover titles quite yet, I love
printed books!

Don't cry for me Curpentino!

If you have to hum something to yourself while programming on your
Mac, this is as good as it gets.

Very long composite picture

This picture I composed from 30 separate shots (RAW 3024 × 1998 pixel each),
originally it was about 60,000 pixels wide,
but I had to resize it to 8,000 because Pixelmator did not allow me to export/merge layers over 8,000 Pixels wide.

Project management tips

1. No taks should be over 4 days long

2. UAT build is on Friday 2 PM, every week, developers plan their task accordingly

3. During UAT deployment and testing phase (code freeze) developers participate in design process

4. All UI features and changes need to be PhotoChopped (wire-framed with OmniGraffle) and reviewed agaist Use Cases before development

Hibernate: Case Insensitive Query

We ran into a situation where we needed to match a string from our application to a string in the database. A very common task. But this time we needed it to be a case insensitive match. In order to do that using Hibernate annotations, we ended up using Restrictions.ilike().

Here is some example code:

public List fetchByCountry(String country)

{

DetachedCriteria criteria = DetachedCriteria.forClass(MobileCarrier.class);

criteria.add(Restrictions.ilike("country", country, MatchMode.EXACT));

return getHibernateTemplate().findByCriteria(criteria);

}

The ilike method is a case insensitive like statement, and when combined with a MatchMode.EXACT, it accomplishes the task of an exact string case insensitive match.

http://10gui.com/video/

This is a concept video of how to effectively incorporate multi-touch into a desktop computer. That part of the video is interesting, but I think the even more revolutionary idea in this video is how they suggest changing the "windowed" approach to the desktop. I can see some pitfalls in what they call "con10uum", but I think it is a great starting point.

I would love to hear anyones thoughts on the topic or if anyone else has links to new types of UI. New UI concepts are very exciting!

Text Messages(SMS) from Emails

Some mobile phone companies allow receiving SMS (Short Messaging Service), MMS (Multimedia Messaging Service) though emails. This means that you can send a SMS to someone from your email account, which means that the sender will not be charged for the SMS transit.

How it works:
1. Create a new email from your email account
2. Mail to address is: mobilenumber@txt.att.net (For AT&T) See: Mobil carriers

3. Check your mobile, and you will receive a new text message

SMS Implementation:

1. create a table MobileMessageType for all the mobil companies that your application will support i.e T-Mobil, AT&T, etc. See: Mobil carriers
2. Create a table MobileMessagingSetting with below fields (add more fields as needed such as max. sms per day):
id
message_type (use MobileMessageType table)
sms_email_to
mms_email_to
3. Create service classes and DAO
4. Create a mailing functionality which send emails to users using his/her mobil number and carrier email address to

Trials and Tribulations of going to GWT 2.0 ms1

Going to GWT 2.0 ms1 is pretty simple for most projects, you just download gwt-2.0.0-ms1 and unzip it.

The one thing you have to do is copy your gwt-dev.jar and rename is as gwt-dev-"your os here".jar (gwt-dev-linux.jar, gwt-dev-mac.jar, gwt-dev-windows.jar). This will be fixed in the next version of GEP.

You can simply add the new GWT sdk in Eclipse.

Now everything should work for you. Unless you have Gilead, prepare to update lots of jars and add many more.

Since Gilead was giving me problems I figured I should update to the latest version gilead-1.2.3.823

In doing that I also needed to update to the latest version of hibernate-annotations-3.4.0GA and hibernate-3.3.2.GA

In turn spring-2.0.8, spring-dao-2.0.8, spring-hibernate3-2.0.8, spring-jdbc-2.0.8, and spring-mock-2.0.8.

Now that that was done I tried to start up the app and got this error that I've documented here http://groups.google.com/group/google-web-toolkit/browse_thread/thread/ca5722230f14f54e?hl=en#

So I added those files and ran into a slew of ClassNotFoundExceptions that led me to find out there were many dependencies that the new gilead, hibernate, and spring needed, so one by one I added the following dependencies.

beanlib-5.0.2beta1

beanlib-hibernate-5.0.2beta1

slf4j-log4j12-1.5.8

slf4j-api-1.5.8

javassist-3.8.0.GA

cglib-2.2

jta-1.1

antlr-2.7.7

jboss-serialization-1.0.3.GA

trove-2.1.0

Once that debacle was over I was up and running GWT 2.0 ms1 below are links to the different jars you will need to download for maven.

User Experience: Quicken totally fails!

I got a copy of Quicken because I was tired of using Google spreadsheet for my budget.

I managed to get my Citibank records imported and manually assign the categories to hundreds of entries in last 6 months to see my spendings by category...

but before that, I went thru the "user experience" nightmare!

1) Selecting the financial institution from hundreds of entries as a drop-down?!? They did not event provide a logo to assure you are selecting the right one.

2) Automatic way of getting your info? Forget it! Of course the they ask you to put in your username and password!!!! What if you select a wrong institution and try to log in, that institution has access to your other account. Bad, really bad.

3) Quicken fails unexpectedly (enven before I had a chance to set up anything):

AppEngine: database annotations JDO or JPA

I am no expert and frankly I don't understand the differences, but
looking at the following comparison it SEEMS like JDO is a better
choice...

One of the concerns would be switching back to Hibernate some day when
DataStore upsets me (and it upsets me a lot).

Please let me know what you decided to use yourself.

GWT: KeyDownHandler listening to key typed

If you want to know when user typed something into the TextBox, or TextArea use KeyDownHandler.

This comes useful when you want to update the SAVE status, or COUNT characters for Twitter (140) or SMS (160).

final TextBox textBox = new TextBox();

textBox.setStyleName("recipe_edit_width");

textBox.setText(currentRecipe.getName());

recipeName.add(textBox);

textBox.addKeyDownHandler(new KeyDownHandler()

{

    public void onKeyDown(KeyDownEvent event)

    {

isSaved = false;

currentRecipe.setName(textBox.getText());

updateSaveStatus();

    }

});
